List Ops

Implement basic list operations.

In functional languages list operations like length, map, and reduce are very common. Implement a series of basic list operations, without using existing functions.

Hints

The foldLeft and foldRight methods are "fold" functions, which is a concept well-known in the functional programming world, but less so in the object-oriented one. See the Wikipedia page on folding for general background and signature/implementation hints.

To run the tests:

$ gradle test

For more detailed info about the Java track see the help page.
